Basal leaves oblanceolate or sometimes spoon-shaped, stalked, 1-15 cm long including the stalks, 1-12 mm wide, sparsely to densely stiff-hairy or nearly glabrous, margins often stiff-hairy; stem leaves similar, becoming linear and reduced upwards.
Heads with ray and disk flowers, borne on the single stem or more often nearly erect branches; involucres 4-9 mm tall; involucral bracts lanceolate, thin, light green, sparsely to moderately stiff-hairy, commonly purplish near the tips, usually graduated; ray flowers white or sometimes pinkish, numerous, 2-3 mm long, slightly surpassing the disk flowers; disk flowers 3.5-5.0 mm long.
